DETAILED DESCRIPTION

Various embodiments of the present invention now will be described more fully hereinafter with reference to the accompanying drawings, in which some, but not all embodiments of the inventions are shown. Indeed, these inventions may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. The term “or” is used herein in both the alternative and conjunctive sense, unless otherwise indicated. The terms “illustrative” and “exemplary” are used to be examples with no indication of quality level. Like numbers refer to like elements throughout. Moreover, while certain embodiments of the present invention are described with reference to predictive data analysis, one of ordinary skill in the art will recognize that the disclosed concepts can be used to perform other types of data analysis.

I. OVERVIEW

Various embodiments of the present invention improve efficiency of performing data evaluation by disclosing techniques that enable targeted data retrieval in order to decrease the amount of data needed to be retrieved prior to performing data evaluation. For example, in some embodiments, a data retrieval engine may limit data retrieval to data deemed related to an input entity (e.g., a patient entity) associated with a particular data evaluation task. By limiting the amount of data needed to be retrieved prior to performing data evaluation, various embodiments of the present invention decrease the computational complexity of data retrieval tasks and (in circumstances where retrieval of data requires utilizing network communications) improve network efficiency of data evaluation architectures that utilize remote data sources. In doing so, various embodiments of the present invention improve efficiency of performing data evaluation.

Furthermore, various embodiments of the present invention address technical challenges related to efficiently and reliably performing data evaluation using distributed data evaluation environments. A distributed data evaluation environment is a software solution configured to perform a data evaluation task using input data retrieved from multiple data sources, often a very large number of data sources. An example of a distributed data evaluation environment is a software solution configured to generate prior authorization determinations for proposed medical operations based on data provided from medical-history-related data sources, medical-claim-related data sources, pharmaceutical-history-related data sources, medical-note-related data sources, and/or the like.

The diversity of input data sources in distributed data evaluation environments presents substantial challenges for software developers that intend to design and deploy data analysis software solutions in the noted distributed data evaluation environments. For example, without employing some degree of parallelism, evaluative data analysis would likely be very inefficient in distributed data evaluation environments because of the often large number of data sources in such distributed data evaluation environments, with the task of data retrieval from the data sources acting as an efficiency bottleneck on the system as a whole.

On the other hand, employing parallelism in such distributed data evaluation environments may lead to other challenges. For example, if the data extraction process is followed by some pre-processing on the data (as is very often the case), coordinating utilization of shared pre-processing resources among various execution in order to avoid deadlock situations threads may be challenging. Thus, various existing distributed data evaluation environments suffer from substantial efficiency and reliability challenges due to the technical challenges identified above as well as similar technical challenges.

Various embodiments of the present invention address the above-noted technical challenges related to efficiently and reliably performing data evaluation in distributed data evaluation environments by providing techniques for parallelized data evaluation that utilize a data-source-specific thread to extract data from each source. By utilizing data-source-specific feature extraction threads, the noted embodiments of the present invention prevent deadlock scenarios where multiple feature threads may attempt to extract data from the same data source and/or using the access interface of the same data source at the same time.

In addition, various embodiments of the present invention address the above-noted technical challenges related to efficiently and reliably performing data evaluation in distributed data evaluation environments by providing techniques for parallelized data evaluation that employ parallelism during data retrieval but limit post-retrieval data processing at the feature-extraction stage to extraction threads configured to retrieve unstructured data from unstructured data sources. By limiting post-retrieval data processing at the feature-extracting-thread level to execution threads configured to retrieve unstructured data from unstructured data sources, various embodiments of the present invention provide protocols for thread coordination that reduce the risk of deadlock scenarios in multi-threaded distributed data evaluation environments.

IV. EXEMPLARY SYSTEM OPERATIONS

As described below, various embodiments of the present invention relate to disclosing techniques for performing data evaluation in a parallelized manner. An exemplary application of the noted parallelized data evaluation concepts relate to determining prior authorization determinations for proposed medical operations. Aspects of the parallelized data evaluation concepts and the automated prior authorization determination concepts are described in greater detail below.

Various embodiments of the present invention utilize the parallelized data evaluation concepts described below to determine prior authorization determinations for proposed medical operations based at least in part on input data associated with corresponding patients related to the proposed medical operations. For example, in some embodiments, the data evaluation computing entity 106 may extract (e.g., using a parallelized data extraction procedure) evidentiary data describing patient history and/or patient demographics of a patient that is subject of a prior authorization task, refine the extracted evidentiary data in accordance with a decision tree data object that describes the pre-authorization requirements for generating a positive prior authorization determination for the noted prior authorization task in order to isolate portions of the extracted evidentiary that relate to the noted pre-authorization requirements, process the refined evidentiary data in accordance with the decision tree data object in order to determine a prior authorization determination for the proposed medical operation, aggregate the refined evidentiary data used to reach the prior authorization determination to generate an explanation output for the prior authorization determination, and present display data related to the prior authorization determination and the explanation output using a prior authorization user interface configured to display prior-authorization-related data to end-users (e.g., to physicians, nurses, hospital staff, and/or the like).

However, while various embodiments of the present invention describe the data evaluation concepts of the present invention in relation to prior authorization determination for proposed medical operations, a person of ordinary skill in the relevant technology will recognize that the data evaluation concepts can be utilized to perform any data evaluation task in an efficient and reliable manner.

FIG. 4 is a data flow diagram of an example process 400 for performing data evaluation of distributed evidentiary data in accordance a shared decision tree data object. Via the various steps/operations of the process 400, the data evaluation computing entity 106 can reduce occurrence likelihood of deadlock scenarios in predictive data analysis systems that utilize distributed input data sources, thus increasing the operational reliability of the noted predictive data analysis systems.

The process 400 begins when a feature extraction engine 401 of the data evaluation computing entity 106 generates shared evidentiary data 411 using a plurality of feature extraction threads. The shared evidentiary data 411 may include a collection of data objects that are deemed related to an input entity, where an input entity may be a data object that describes a real-world entity and/or a real-world phenomenon with respect to which data evaluation is performed. For example, the shared evaluation data may include medical history data of a patient input entity. The shared evidentiary data 411 may be generated based on input data stored on the storage subsystem 108 and/or storage data provided by a client computing entity 102.

The feature extraction engine 401 may generate the shared evidentiary data 411 based on data retrieved from a plurality of evidentiary data sources (not depicted). An evidentiary data source may be any storage platform and/or portion of a storage platform that stores at least one of one or more data assets including evidentiary data associated with one or more input entities. Examples of data sources include clinical data sources, medical claims data sources, lab results data sources, pharmaceutical history data sources, medical note data objects (e.g., physician-generated medical note data objects) and/or the like. In some embodiments, to retrieve data from the plurality of evidentiary data sources, the feature extraction engine 401 utilizes a plurality of feature extraction threads, where each feature extraction thread may be configured to retrieve evidentiary data associated with a target input entity from an evidentiary data source of the plurality of evidentiary data sources that is associated with the feature extraction thread.

In some embodiment, retrieval of data by the feature extraction threads is performed by data extraction policies that are defined in accordance with the data evaluation. For example, when a data evaluation pertains to a particular patient entity, the feature extraction threads may be configured to retrieve structured data and unstructured data deemed related to the particular patient entity. In some embodiments, retrieval of data by the feature extraction threads is performed by data extraction policies that are defined in accordance with at least a subset of nodes of a decision tree associated with the data evaluation. For example, when a data evaluation pertains to a medical data evaluation subject, the decision tree of the data evaluation may describe the medical data evaluation subject association of the data evaluation, and the threads may be configured to retrieve structured data and unstructured data deemed related to medical information of the particular patient entity.

In some embodiments, to generate the shared evidentiary data 411, the feature extraction engine 401 performs the steps/operations of the process depicted in FIG. 5 . As depicted in FIG. 5 , at step/operation 501, the feature extraction engine 401 causes each structured feature extraction thread of one or more feature extraction threads to extract corresponding retrieved feature data from corresponding structured data source of one or more structured data sources that is associated with the structured feature extraction thread. A structured data source may be a data source that stores structured data, where structured data may include a collection of data objects that are organized in a manner that clearly indicates the relationships between the data objects. Examples of structured data include data stored in at least one of relational databases, graph-based databases, object-oriented databases, and/or the like. A structured feature extraction thread may be a feature extraction thread that is configured to extract data from a structured data source that is associated with the structured feature extraction thread.

At step/operation 502, the feature extraction engine 401 causes each unstructured feature extraction thread of one or more unstructured feature extraction threads to extract corresponding unstructured feature data from an unstructured data source of one or more unstructured data sources. An unstructured data source may be a data source that stores unstructured data, where unstructured data may include a collection of data objects that are not organized in a manner that clearly indicates the relationships between the data objects. Examples of unstructured data include natural language data, such as natural language medical note data.

Operational examples of structured data sets and unstructured data sets are depicted in FIG. 13 . FIG. 13 displays four data sets, three of which are structured data sets and one of which is an unstructured data set. In particular, the four sets displayed in FIG. 13 include a medical claims data set 1301 that is a structured data set, a clinical notes data set 1302 that is an unstructured natural language data set, a lab results data set 1303 that is a structured data set, and a pharmaceutical history data set 1304 that is a structured data set.

Returning to FIG. 5 , at step/operation 503, the feature extraction engine 401 causes each unstructured feature extraction thread of the one or more unstructured feature extraction threads to process corresponding per-source unstructured feature data for the unstructured feature extraction thread using a shared feature processing interface to generate per-source engineered feature data for the unstructured feature extraction thread.

In some embodiments, the feature extraction engine 401 causes each unstructured feature extraction thread to utilize a shared feature processing interface accessible by all of the unstructured feature extraction threads in order to generate, based on the corresponding per-source unstructured feature data for the unstructured feature extraction thread, per-source engineered feature data for the unstructured feature extraction thread, where the per-source engineered feature data for an unstructured feature extraction thread may include a collection of structured data objects generated by processing the corresponding per-source unstructured feature data for the unstructured feature extraction thread using the shared feature processing interface.

The shared feature processing interface may include a collection of computer-implemented processes configured to generate inferred structured data based on input unstructured data. An example of a shared feature processing interface is a shared natural language processing (NLP) engine comprising one or more NLP processes configured to generate inferred structured data based on input unstructured natural language data. For example, a shared NLP engine may be configured to extract metadata (e.g., associated patient identifiers, associate diagnosis codes, associated operational codes, and/or the like) from natural language medical note documents.

In some embodiments, step/operation 503 may be performed on a per-unstructured-thread level in accordance with the process depicted in FIG. 6 . As depicted in FIG. 6 , at step/operation 601, an unstructured feature extraction thread determines a feature-relevant subset of per-source unstructured feature data for the particular unstructured feature extraction thread. The feature-relevant subset of the per-source unstructured feature data for the unstructured feature extraction thread may be a collection of data objects from the per-source unstructured feature data that are deemed with certainty to be associated with an input entity subject to the data evaluation. For example, a feature relevant subset may include medical note documents that are deemed with certainty to be associated with a patient input entity subject to the data evaluation.

At step/operation 602, the particular unstructured feature extraction thread determines a potentially feature-relevant subset of per-source unstructured feature data for the unstructured feature extraction thread. The potentially feature-relevant subset of the per-source unstructured feature data for the unstructured feature extraction thread may be a collection of data objects from the per-source unstructured feature data that are deemed with some degree of uncertainty to be associated with an input entity subject to the data evaluation. For example, a feature relevant subset may include medical note documents that are deemed with some degree of uncertainty to be associated with a patient input entity subject to the data evaluation.

At step/operation 603, the unstructured feature extraction thread generates per-source engineered feature data for the unstructured feature extraction thread based on at least one of the feature-relevant subset for the unstructured feature extraction thread and the potentially feature-relevant subset for the unstructured feature extraction thread. In some embodiments, the unstructured feature extraction thread combines the feature-relevant subset for the unstructured feature extraction thread and at least a portion of the potentially feature-relevant subset for the unstructured feature extraction thread to generate the per-source engineered feature data for the unstructured feature extraction thread.

In some embodiments, step/operation 603 may be performed in accordance with the process depicted in FIG. 7 . As depicted in FIG. 7 , at step/operation 701, the unstructured feature extraction thread determines confirmation data for the potentially feature-relevant subset. The confirmation data may include a collection of data objects that describe, for each data object in the potentially feature-relevant subset, whether association of the data object with an input entity subject to the data evaluation has been confirmed by a secondary authority (e.g., a secondary authority using human-generated data, such as physician confirmatory data, provider confirmatory data, insurance confirmatory data, and/or the like).

At step/operation 702, the unstructured feature extraction thread identifies a confirmed subset of potentially-relevant subset based on the confirmation data. In some embodiments, the confirmed subset includes each potentially relevant data object in the potentially-relevant subset whose association with an input entity subject to the data evaluation has been confirmed by at least one data object in the confirmation data. In some embodiments, the confirmed subset includes each potentially relevant data object in the potentially-relevant subset whose association with an input entity subject to the data evaluation has been confirmed by a predefined threshold number of data objects in the confirmation data. In some embodiments, the confirmed subset includes each potentially relevant data object in the potentially-relevant subset whose association with an input entity subject to the data evaluation has been confirmed by a predefined threshold ratio of data objects in the confirmation data. In some embodiments, the confirmed subset includes each potentially relevant data object in the potentially-relevant subset whose association with an input entity subject to the data evaluation has been confirmed by a predefined threshold ratio of data objects related to the potentially relevant data object in the confirmation data.

At step/operation 703, the unstructured feature extraction thread generates the per-source engineered feature data for the unstructured feature extraction thread based on the feature-relevant subset for the unstructured feature extraction thread and the confirmed subset of the potentially feature-relevant subset the unstructured feature extraction thread. In some embodiments, the unstructured feature extraction thread combines the following two sets of unstructured data objects in order to generate an aggregated set of unstructured data objects deemed related to an input entity subject to the data evaluation: (i) the set of unstructured data objects (e.g., medical note documents) deemed with certainty to be related to the input entity; and (ii) the set of unstructured data objects deemed with some degree of uncertainty to be related to an input entity subject to the data evaluation and who have been confirmed by the confirmation data in order to provide a selected set of unstructured data objects deemed. Thereafter, the unstructured feature extraction thread may utilize the aggregated set of unstructured data objects to generate per-source engineered feature data for the unstructured feature extraction thread.

Returning to FIG. 5 , at step/operation 504, the feature extraction engine 401 aggregates each per-source retrieved feature data extracted by a structured feature extraction thread of the one or more structured feature extraction threads and each per-source engineered feature data generated by an unstructured feature extraction thread of the one or more unstructured feature extraction threads to generate the shared evidentiary data 411. In some embodiments, the feature extraction engine 401 combines structured data retrieved from structured data sources by structured feature extraction threads and engineered structured data generated based on unstructured data retrieved unstructured data sources by unstructured feature extraction threads to generate the per-source retrieved feature data.

An operational example of a process 1100 for thread coordination by the feature extraction engine 401 is depicted in FIG. 11 . As depicted in FIG. 11 , the feature extraction engine 401 causes each structured feature extraction thread 1101A-N to retrieve structured data from a respective structured data source 1102A-N. For example, the feature extraction engine 401 causes the structured feature extraction thread 1101A to retrieve structured data from a respective structured data source 1102A, the structured feature extraction thread 1101B to retrieve structured data from a respective structured data source 1102B, and the structured feature extraction thread 1101N to retrieve structured data from a respective structured data source 1102N.

Furthermore, the feature extraction engine 401 causes each unstructured feature extraction thread 1103A-N to retrieve unstructured data from a respective unstructured data source 1104A-N and to process the retrieved structured data using a shared feature processing interface 1105 to generate corresponding engineered structured data.

For example, the feature extraction engine 401 causes the unstructured feature extraction thread 1103A to retrieve unstructured data from a respective unstructured data source 1104A and to process the retrieved structured data using a shared feature processing interface 1105 to generate corresponding engineered structured data. As another example, the feature extraction engine 401 causes the unstructured feature extraction thread 1103B to retrieve unstructured data from a respective unstructured data source 1104B and to process the retrieved structured data using a shared feature processing interface 1105 to generate corresponding engineered structured data. As a further example, the feature extraction engine 401 causes the unstructured feature extraction thread 1103N to retrieve unstructured data from a respective unstructured data source 1104N and to process the retrieved structured data using a shared feature processing interface 1105 to generate corresponding engineered structured data.

Moreover, the feature extraction engine 401 may in some embodiments cause each unstructured feature extraction thread 1103A-N to generate the engineered structured data generated for the unstructured feature extraction thread 1103A-N to the feature extraction engine 401.

For example, the feature extraction engine 401 causes the unstructured feature extraction thread 1103A to generate the engineered structured data generated for the unstructured feature extraction thread 1103A to the feature extraction engine 401. As another example, the feature extraction engine 401 causes the unstructured feature extraction thread 1103B to generate the engineered structured data generated for the unstructured feature extraction thread 1103B to the feature extraction engine 401. For example, the feature extraction engine 401 causes the unstructured feature extraction thread 1103N to generate the engineered structured data generated for the unstructured feature extraction thread 1103N to the feature extraction engine 401.

Returning to FIG. 4 , subsequent to generating the shared evidentiary data 411, the feature extraction engine 401 provides the shared evidentiary data 411 to the evidence refinement engine 402 of the data evaluation computing entity 106. The evidence refinement engine 402 is configured to refined evidentiary data 412 based on a selected evidentiary data subset of the shared evidentiary data 411 that correspond to one or more selected nodes of the shared decision tree data object. The shared decision tree data object may be a data object that describes one or more evaluation criteria for a particular data evaluation. The shared decision tree data object may further be associated with a sufficiency criterion that describes one or more combinations of the evaluation criteria described by the shared decision tree data object that satisfy the requirements of the particular data evaluation associated with the shared decision tree data object.

For example, a shared decision tree data object may have five evaluation criteria EC₁, EC₂, EC₃, EC4₄, and EC₅. An example sufficiency criterion for the shared decision tree data object may describe that, to satisfy the requirements of the particular data evaluation associated with the shared decision tree data object, the refined evidentiary data must satisfy at least three of the noted five evaluation criteria. Another example sufficiency criterion for the shared decision tree data object may describe that, to satisfy the requirements of the particular data evaluation associated with the shared decision tree data object, the refined evidentiary data must satisfy either at least three of the noted five evaluation criteria if the refined evidentiary data does not satisfy the first evaluation criterion EC₁ and at least two of the noted five evaluation criteria if the refined evidentiary data satisfies the first evaluation criterion EC₁. A yet another example sufficiency criterion for the shared decision tree data object may describe that, to satisfy the requirements of the particular data evaluation associated with the shared decision tree data object, the refined evidentiary data must satisfy the first evaluation criterion EC₁ and at least three other evaluation criteria of the five noted evaluation criteria. A further example sufficiency criterion for the shared decision tree data object may describe that, to satisfy the requirements of the particular data evaluation associated with the shared decision tree data object, the refined evidentiary data must satisfy both of at least one of the first evaluation criterion EC₁ and the second evaluation criterion EC₂ and at least two other evaluation criteria of the five noted evaluation criteria.

An operational example of evaluation criteria data object 1200 that can be used to generate a shared decision tree data object is presented in FIG. 12 . As depicted in FIG. 12 , the evaluation criteria data object 1200 include nine evaluation-criteria-related segments 1201 and two sufficiency-criterion-related portions 1202. In some embodiments, the data evaluation computing entity 106 may utilize the evaluation criteria data object 1200 to generate a shared decision tree data objects with nine leaf nodes corresponding to the nine evaluation-criteria-related segments 1201 of the evaluation criteria data object 1200 and a sufficiency criterion indicating that at least one of the nine leaf nodes must be met for the shared decision tree data object to be deemed satisfied. In some embodiments, the data evaluation computing entity 106 may combine evaluation criteria information from two or more evaluation criteria data objects to generate a shared evaluation data object. In some embodiments, the data evaluation computing entity 106 may receive the shared decision tree data object from a client computing entity 102 and/or from an external computing entity.

The refined evidentiary data 412 may include a subset of the shared evidentiary data 411 that correspond to the evaluation criteria described by the shared decision tree data object for the data evaluation. In some embodiments, generating the refined evidentiary data comprises identifying, based on the shared decision tree data object, one or more evaluation criterion data objects, wherein each evaluation criterion data object of the one or more evaluation criterion data objects corresponds to a selected node of the selected nodes of the shared decision tree data object; determining a classification-relevant subset of the shared evidentiary data that correspond to the one or more evaluation criterion data objects; and generating the refined evidentiary data based on the classification-relevant subset.

After generating the refined evidentiary data 412, the evidence refinement engine 402 provides the refined evidentiary data 412 to the evaluation engine 403 of the data evaluation computing entity 106. The evaluation engine 403 may be configured to process the refined evidentiary data in accordance with the shared decision tree data object to generate an evaluation output 413 and an explanation output 414.

The evaluation output 413 may be a data object that indicates whether the input entity subject to the data evaluation satisfies the requirements of the data evaluation. To generate the evaluation output 413, the evidence refinement engine 402 may determine whether the refined evidentiary data 412 satisfy the requirements described by the evaluation criteria of the shared decision tree data object and the sufficiency criterion of the shared decision tree data object. In some embodiments, the input entity is a patient input entity, the shared evidentiary data comprises medical history data of the patient input entity, the shared decision tree data object describes authorization criteria for a proposed medical operation, and the evaluation output describes an authorization determination for the proposed medical operation with respect to the patient input entity.

In some embodiments, the evaluation engine 403 may generate the evaluation output 413 in accordance with the various steps/operations of the process depicted in FIG. 8 . As depicted in FIG. 8 , at step/operation 801, the evaluation engine 403 determines a per-criterion evaluation for each evaluation criterion of one or more evaluation criteria described by the shared decision tree data object based on the refined evidentiary data 412. The per-criterion evaluation for an evaluation criterion may be a data object that describes whether the refined evidentiary data 412 provides sufficient evidence indicating that the evaluation criterion has been satisfied.

For example, if an evaluation criterion requires history of heart failure, the per-criterion evaluation for the evaluation criterion may indicate whether refined evidentiary data 412 describing medical history of a corresponding patient input entity describes a history of heart failure in relation to the corresponding patient input entity. As another example, if an evaluation criterion requires chronic kidney disease, the per-criterion evaluation for the evaluation criterion may indicate whether refined evidentiary data 412 describing medical condition of a corresponding patient input entity describes chronic kidney disease in relation to corresponding patient input entity. As yet another example, if an evaluation criterion requires at least 45 years of age, the per-criterion evaluation for the evaluation criterion may indicate whether refined evidentiary data 412 describing demographic information of a corresponding patient input entity describes that the corresponding patient input entity is at least 45 years of age.

At step/operation 802, the evaluation engine 403 a positive evaluation subset of the one or more evaluation criteria described by the shared decision tree data object based on each per-criterion evaluation for an evaluation criterion of the one or more evaluation criteria. In some embodiments, the positive evaluation subset comprises each evaluation criteria described by the shared decision tree data object that the refined evidentiary data 412 indicates as having been satisfied by the shared evidentiary data 411.

For example, in some embodiments, if an evaluation criterion requires chronic kidney disease, and further if the per-criterion evaluation for the evaluation criterion indicates that refined evidentiary data 412 describes that a corresponding patient input entity has chronic kidney disease, the evaluation criteria will be in the positive evaluation subset of the one or more evaluation criteria described by the shared decision tree data object. As another example, if an evaluation criterion requires at least 45 years age, and further if the per-criterion evaluation for the evaluation criterion indicates that refined evidentiary data 412 describes that a corresponding patient input entity is 55 years of age, the evaluation criteria will be in the positive evaluation subset of the one or more evaluation criteria described by the shared decision tree data object.

At step/operation 803, the evaluation engine 403 generates the evaluation output 413 based on whether the positive evaluation subset satisfies a sufficiency criterion for the shared decision tree data object. In some embodiments, the sufficiency criterion is a data object describes a threshold count of evaluation criteria described by the shared decision tree data object. In some of the noted embodiments, the evaluation output 413 describes whether the count of evaluation criteria in the positive evaluation subset satisfies the threshold count of evaluation criteria described by the sufficient criterion. In some embodiments, the sufficiency criterion is a data object describes one or more acceptable evaluation criteria combinations. In some of the noted embodiments, the evaluation output 413 describes whether at least one of the evaluation criteria in the positive evaluation subset corresponds to at least one of the one or more acceptable evaluation criteria combinations described by the sufficient criterion. In some embodiments, the sufficiency criterion is a data object describes one or more required properties of acceptable evaluation criteria combinations. In some of the noted embodiments, the evaluation output 413 describes whether at least one of the evaluation criteria in the positive evaluation subset satisfies at least one of the one or more required properties of acceptable evaluation criteria combinations described by the sufficient criterion.

The explanation output 414 may be a data object that describes at least one mapping between at least a portion of the shared evidentiary data 411 and at least a portion of the evaluation criteria described by the shared decision tree data object. For example, the explanation output 414 may describe which portions of the refined evidentiary data 412 are used as support to reach a determination that a corresponding input entity has satisfied a particular evaluation criterion described by the shared decision tree data object and/or has failed to satisfy a particular evaluation criterion described by the shared decision tree data object. As another example, the explanation output 414 may describe which evaluation criteria described by the shared decision tree data object have been satisfied by the refined evidentiary data 412 and/or which evaluation criteria described by the shared decision tree data object have not been satisfied by the refined evidentiary data 412.

In some embodiments, the evaluation engine 403 may generate the explanation output 414 in accordance with the various steps/operations of the process depicted in FIG. 9 . As depicted in FIG. 9 , at step/operation 901, the evaluation engine 403 determines a per-criterion evaluation for each evaluation criterion of one or more evaluation criteria described by the shared decision tree data object based on the refined evidentiary data 412. The per-criterion evaluation for an evaluation criterion may be a data object that describes whether the refined evidentiary data 412 provides sufficient evidence indicating that the evaluation criterion has been satisfied.

For example, if an evaluation criterion requires history of heart failure, the per-criterion evaluation for the evaluation criterion may indicate whether refined evidentiary data 412 describing medical history of a corresponding patient input entity describes a history of heart failure in relation to the corresponding patient input entity. As another example, if an evaluation criterion requires chronic kidney disease, the per-criterion evaluation for the evaluation criterion may indicate whether refined evidentiary data 412 describing medical condition of a corresponding patient input entity describes chronic kidney disease in relation to corresponding patient input entity. As yet another example, if an evaluation criterion requires at least 45 years of age, the per-criterion evaluation for the evaluation criterion may indicate whether refined evidentiary data 412 describing demographic information of a corresponding patient input entity describes that the corresponding patient input entity is at least 45 years of age.

At step/operation 902, the evaluation engine 403 identifies a criterion-related subset of the refined evidentiary data 412 for each evaluation criterion of one or more evaluation criteria described by the shared decision tree data object. A criterion-related subset associated with an evaluation criterion may be a data object that describe at least one portion of refined evidentiary data 412 that is determined to include information deemed pertinent to determining whether the refined evidentiary data 412 satisfy the evaluation criterion. For example, if an evaluation criterion relates to medical history, the per-criterion subset for the evaluation criterion may be extracted from the medical history data of a corresponding patient input entity. As another example, if an evaluation criterion relates to prescription history, the per-criterion subset for the evaluation criterion may be extracted from the prescription history data of a corresponding patient input entity. As yet another example, if an evaluation criterion relates to patient age, the per-criterion subset for the evaluation criterion may be extracted from the patient profile data and/or patient demographic data of a corresponding patient input entity.

At step/operation 903, the evaluation engine 403 generates the explanation output 414 based on each per-criterion evaluation for an evaluation criterion and each criterion-related subset for an evaluation criterion. In some embodiments, the evaluation engine 403 combine at least a portion of on each per-criterion evaluation for an evaluation criterion and at least a portion of each criterion-related subset for an evaluation criterion in order to generate the explanation output 414. For example, the evaluation engine 403 may combine all of on each per-criterion evaluation for an evaluation criterion and all of each criterion-related subset for an evaluation criterion in order to generate the explanation output 414.

Returning to FIG. 4 , subsequent to generating the evaluation output 413 and the explanation output 414, the evaluation engine 403 provides the evaluation output 413 and the explanation output 414 to the display engine 404. The display engine 404 is configured to display (e.g., using a decoupled user interface module) an evaluation output user interface 415 comprising display data describing the evaluation output and the classification explanation output. In some embodiments, the display engine 404 provides user interface data associated with the evaluation output user interface 415 to a client computing entity 102, where the user interface data may be a collection of data objects that contains display data (e.g., Hyper-Text Markup Language (HTML) data) that can be executed to display the evaluation output user interface 415.

An operational example of the evaluation output user interface 415 is presented in FIG. 10 . As depicted in FIG. 10 , the evaluation output user interface 415 of FIG. 10 displays the evaluation output 1001 at the top-right edge of the evaluation output user interface 415 and the data evaluation subject matter 1002 at the top-center of the evaluation output user interface 415.

As further depicted in FIG. 10 , the evaluation output user interface 415 of FIG. 10 displays per-criterion evaluations for relevant evaluation criteria in the main region 1003 of the evaluation output user interface 415. Selecting an interactive portion of a per-criterion-evaluation such as the per-criterion evaluation 1004 may lead to display of information associated with the per-criterion-evaluation, such as the relevant diagnosis code information 1005 for an evaluation criterion associated with the per-criterion evaluation 1004 and criterion-related evidentiary data objects 1006 for the evaluation criterion associated with the per-criterion evaluation 1004. Moreover, selecting an interactive portion of a criterion-related evidentiary data object such as the criterion-related evidentiary data 1007 may lead to display of information associated with the criterion-related evidentiary data, such as a text version and/or an image version of the criterion-related evidentiary data 1007.

In some embodiments, the data evaluation computing entity 106 may perform one or more evaluation-based actions based on at least one of the evaluation output 413 and the explanation output 414. For example, the data evaluation computing entity 106 may grant and/or deny pre-authorization for a proposed medical operation based on the evaluation output 413.
